Buy CCI Aps Strips #250 Large Rifle Magnum Online. You can now prime brass quickly and easily thanks to a collaboration between CCI and its sister firm, RCBS, which makes the APS Bench Priming Tool and other auto priming equipment. For continuous loading, numerous self-feeding, self-lubricating strips can be joined together; each strip stores 25 primers. The possibility of contamination is decreased because the primers are already placed into the strips. The APS Primer Strip Loader allows for the reloading of primer strips. CCI Primers are evaluated and refined throughout time. Because of this, CCI primers available today are more sensitive, simpler to seat, and compatible with progressive and automated loading equipment than ever before. For the cleanest burn possible, they use contemporary non-corrosive and non-mercuric initiator blends.
